Abstract
An ultrasonic processing method by which polymer/drug composites can be quickly and efficiently molded to form matrix-type drug delivery systems is disclosed. The advantages of the method include speed and good control of the process. It also causes less degradation in polymers and/or drugs than most conventional processing methods.
